We must resume our narrative of Madame de Hell's journey. On their way to Stavropol, they experienced a mountain-storm, one of the grandest and most terrible they had ever witnessed. The roar of the thunder, repeated by every echo in cavern and ravine, mingled with the groaning and jarring of the great trees, with the loud gusts of the furious wind, with all those mysterious voices of the tempest which come we know not whence, but deeply stir the heart, and have so potent a harmony and such a sublimity and force of sound that the least superstitious mind involuntarily awaits some supernatural manifestation, some message from the other world. We have ourselves listened to a storm in a Highland glen--the wind sweeping down the rugged declivities with terrible impetuosity, and the thunder-peals reverberating from peak to peak, while the clouds "From many a horrid rift abortive poured Fierce rain with lightning mixed, water with fire," until the sense of an eerie and mysterious Presence has forced itself upon our mind, and we have been able to understand the emotions in which originated the visions of wraith and phantom of the bards of old. Our travellers, however, passed through the gale unhurt. A tremendous outburst of rain, the final effort of the tempest, cleared the sky, which towards the west was gradually lighted up with gleams of purple light, contrasting gloriously with the darkness of the rest of the firmament. A gorgeous rainbow, one foot of which rested on the highest peak of the Caucasus, while the other was enveloped in the mists of evening, rose before them for a few moments, like an image of hope, and then slowly faded into thin air. At length they reached the station, but in an unpleasant condition--wet, weary, dazed, and not a little surprised to find themselves safe and sound after the adventures of the day. * * * * *
